TIME-TABLE.

Specification of Letters Patent. I

Patented Feb. 11, 1919.

Application filed May 9, 1916. Serial No. 96,268.

T 0 all whom it may concern:

Be it known that I, THOMAS Noni. Pour.- LAIN, a citizen of the United States, residing at Claymont, in the county of New Castle and State of Delaware, have invented certaln new and useful Improvements in Time- Tables, of which the following is a specification.

The principal object of the present invention is to facilitate the use of time-tables, and in accordance with the present invention this object is attained by the provision of improved means for identifying each of the stations in the vertical station column with the train times in the horizontal row of train times which relate thereto, even at points remote from the station column.

The invention will be claimed at the end hereof but will be first described in connection with the accompanying drawing forming part hereof and in which is illustrated a portion of a time table embodying features of the invention and also a legend constituting a color chart.

In the drawings T is a time-table having printed thereon in horizontal rows 1, 2, 3, 4c, 5, the names of stations followed by the times of trains. The names of the stations are arranged in a vertical column 6. One such vertical column is shown at or near the left hand margin, but additional columns may be employed. R, B, Y, G, and L, are

underscore lines, one for each horizontal row. The underscore lines for adjacent horizontal rows are in contrasting colors. The number of contrasting colors employed is not limited but I have shown five, the underscore line B, being red, the underscore line B, being blue, the underscore line Y, being yellow, the underscore line G, being green, and the underscore line L, being lavender. The designations A. M. and P. M. appear in 'contrasting colors, A. M. being in red and P. M. being in blue.

In use the color of the underscore line appertaining to any station, affords an easy means for tracing the train times that appertain to that station all the way across the sheet and for identifying them and distinguishing them from ad acent train times that appertain to other stations.

What I claim is:

A time-table provided with a clear ground having printed thereon in horizontal rows the names of stations followed by the times of trains, the names of stations being in vertical column, and having thereon underscore lines for each row, the underscore lines of adjacent rows being in contrasting colors, whereby the train times appertaining to any station can be identified and distinguished at parts of the sheet remote from the column.
